vellum fluids is xpbd, more suitable for small-scale fluids sim, and flip is a mix of fields&points(PIC) which is much more efficient when dealing with large-scale sim(Not saying that you can't use them for one another, as long as there are good reasons to do so). They're good for different purposes and each has its own limitations on both the algorithms&implementation sides.
@@lewisorton713 oh sorry I totally miswrote. My question actually was if pop fluids still has a purpose with vellum fluids existing now! Sorry about the confusion! :D
@@lewisorton713 hi thanks alot with the reply, I has not look into houdini 19 yet , also not sure if they remove pop fluid in houdini 19, but still interested to learn and understand pop fluid in the older version. currently just do not really understand '10 layer of particle' in 5:54 thanks in advance for the explaination
@@zhengshu8925 Sure. Think about the concept of 'thickness of fluid' which equals to the diameter of one particle times the count of layers. '10 layers of particles' means when your fluid has at least 10 particles stacked from top to bottom when viewing from the side.
Still relevant even today, thanks Lewis!
Amazing tutorial. Thank you very much!
Good, thank you.
Thank you!
Really good explonation, thank you :)
Do you know how to mix colorful liquids with this method?
Any idea on how to use adaptative viscosity w POP Fluid node? Thanks Lewis!
With Vellum fluids, is there still a good reason to use flip fluids? Or not really?

@@Handcraftedcc pop fluid is fully integrated into vellum fluid deep down in the core, you should always use vellum fluid from now on.
hi Its me again, I encounter a jitter, wanna ask do you know what is causing it?,
5:54 could anyone explain what he mean by 10 layer of particles?
Hi there, technically you can just use the vellum fluid in H19 without using pop fluid as shown here, pdb fluid is implemented in Vellum since H19.

@@lewisorton713 ahh, ok got it, thanks you so much for your time. much appreciate
